looking for info on a TRW L2018F piston. supposed to be a stock profile flat top piston for a 312 Ybock standard bore 3.80" or in other words, a .050 over 292 piston.

is this a forged piston?

i know TRW is no longer around and is now speed pro. i don't see it in any speed pro catalog..

i'm looking for a forged flat top stock profile 312 Y-block piston in std bore.

With 312 rods and a 312 crank (ECZ) you don't have to cut the piston tops, the deck height is about right as is, if you buy aftermarket forged pistons the rods do not need to be narrowed and will be full floating (no need to cut for pin retainers) and yes they still make standard sizes.

Excellent thread. I only wish I would have known all this 7 years ago when I dropped a 312 crank in my 292.   I could have saved .023" of good iron from both decks. After removing that amount from each deck, the pistons were still .009" in the hole.
